API Tank Standards Update PETRO 2012 May 28 - 31, 2012 Alexandria, Virginia Steve Crimaudo, Senior Associate API Standards The subject of this presentation is a currently active project to rewrite API Recommended Practice 575, Inspection of Atmospheric and Low-Pressure Storage Tanks The objectives of the rewrite project are to update current information in the recommended practice, and to add new information on inspection techniques and leak tightness considerations API documents are reviewed and updated on a five-year cycle The timing for the current update of RP 575 is particularly appropriate because inspection technology has advanced since the last edition, use of API Std 653, Tank Inspection, Repair, Alteration, and Reconstruction, continues to grow, and with that growth more questions have arisen on what should be done during a tank inspection Revisions being developed to RP 575 are based on a broad spectrum of input However, they have yet to presented, discussed, and balloted These steps will occur later this year, with publication anticipated by the end of the year

API History 1919: API founded as non-profit national trade association, New York City 1980s: API relocates to Washington, DC 1995: API Dallas Standards Office relocates to Washington, DC 2007: Opened first of 3 planned international offices in Beijing, China 2011: Singapore and Dubai, UAE offices opened

Background on API Standards Program The API Standardization Department was formed in 1923, with the first API standard published the following year on drilling threads. All industry segments now active in standardization: Exploration and Production Pipeline Transportation Refining Marketing

API Standards API now publishes ~600 technical standards covering all aspects of the oil and natural gas industry Foundation of Self Supporting Programs Basis for Worldwide Operations Core of Institute’s Technical Authority

Standards Development Process The API Standards program is accredited by the American National Standards Institute (ANSI) – the program was reaccredited by ANSI in Oct. 2011 following a 2010 audit. - Openness, Balance, Consensus, Due Process - Regular program audits (conducted by ANSI) Transparent process (anyone can comment on any document in process) - All comments must be considered

Standards Development Process Developed by consensus (does not mean unanimity) Committee balance between users/owner operators, manufacturers and contractors/consultants Standards developed using ANSI approved API Standards Development Procedures (available on-line at www.api.org) API corporate membership is not a requirement for participation on API standardization committees. Support from your management to participate is.

Use of API Standards “De facto” international standards Adoption by reference common by State and Federal agencies – BOEMRE, DOT and EPA API does not promote adoption - prefer voluntary use Written for flexibility as performance based documents For 2012 the ongoing goal is to focus on documents with related policy impact.

AST Standards - History [From 653 - Annex A: Background on Past Editions of API Welded Storage Tank Standards] API published a specification for welded steel storage tanks in July 1936 entitled API Standard 12C, All-Welded Oil Storage Tanks. Fifteen editions and seven supplements to API 12C were published between 1936 and 1958. API 12C was replaced by API Standard 650, Welded Tanks for Oil Storage in December 1961; 11 editions and 22 supplements, revisions or addenda to API 650 have been issued since.

Design & Construction API 620, Design and Construction of Large, Welded, Low-Pressure Storage Tanks Designed for metal temperatures not greater than 250°F and with pressures in their gas or vapor spaces not more than 15 lbf/in. sq. gauge Appendix Q covers liquefied gases at temperatures not lower than –325°F Appendix R covers refrigerated products at temperatures from +40°F to –60°F

Current Edition of API 620 API 620, Design and Construction of Large, Welded, Low-pressure Storage Tanks, 11th Edition Addendum 3 to the 11th Edition was published March 2012

API Standard 625 - Tank Systems for Refrigerated, Liquified Gas Storage API 625 is a proposed new standard for refrigerated tank systems which addresses coordination of the components of the tank system so that they act in an integrated way.   The three related standards (API 625, API 620 and ACI 376) when all are published will bring American standards up to date with coverage of the single, double and full containment concepts which are currently in use.

API Standard 625 - Tank Systems for Refrigerated, Liquified Gas Storage API 625, Tank Systems for Refrigerated Liquefied Gas Storage 1st Edition was published August 2010

Tank Design & Construction API 650, Welded Tanks for Oil Storage Primary construction code for refinery and storage terminal AST’s Covers material, design, fabrication, erection and testing requirements For tanks whose entire bottom is uniformly supported

Current Edition of API 650 API 650, Welded Tanks for Oil Storage 11th Edition, Addendum 3, published August, 2011  Errata to Addendum 3 to incorporate additional revisions were published October 2011
